If you are unable to resolve the situation, next speak to the session owner (Host of the session) and let them know what's going on. By default, the host has a yellow star badge on their name plate, though some users choose to hide or otherwise modify their visible badges. The yellow star badge will always be visible next to the host's name in the Users tab of the Session section of the Dash menu. The host has many capabilities for managing their session. See #Session Owner Moderation.
